Epub 2007 Jun 13. Foam typically occurs in blending, mixing, distillation, fermentation, filtration and filling processes. The main acti. The generation of foam during fermentation processes is caused by the existence of foam-active substances in the fermentation broth, escaping gas/air and turbulences within the fermenter. Antifoams can also control foam during the downstream separation of fermentation products from fermentation broth. Invariably, the resulting foam impairs product properties in many different ways and greatly disrupts the process flow. a process for the fermentation production of an amino acid, a carboxylic acid, an enzyme or an antibiotic, which com prises adding an antifoaming agent for fermentation, Said agent containing the above components (A) and (B), to a culture medium in an amount of 0.0001 to 2 wt.% and culturing a microorganism in the resulting culture medium. 56 0 obj <>stream This affects the normal operation. 3mQC+pMfB+Tg6 |Z"2f(( Abstract. endobj All aerobic fermentations need and use antifoams.
